What is Sea Level Pressure?

Sea level pressure is the surface pressure standardized to sea level. By adjusting surface pressure readings to sea level, meteorologists can create accurate and comparable global maps of atmospheric pressure, for use  in weather prediction and analysis.  It’s a critical metric in weather for understanding the strength and movement of high and low-pressure systems across the globe. 

What is the Impact of Sea Level Pressure?

Sea level pressure is instrumental in identifying and tracking weather systems It influences wind patterns, temperature, and precipitation, playing a key role in the global climate system. Variations in sea level pressure are associated with weather changes, affecting conditions experienced locally and regionally.
